Named after the feisty Byzantine empress, this is one of İstanbul's most impressive boutique hotels. The four buildings house 26 diverse rooms joined by lots of stairs. The enticing garden suites overlook a gorgeous flower-filled courtyard where breakfast is served in warm weather. You can enjoy an early evening drink there, or while admiring the sea view from the terrace.
Note that rates on the hotel website are usually cheaper than those on other booking sites.
